T-Mobile Opens Up on Its Cybersecurity Transformation in New Report

Jeff Simon, EVP & Chief Information Officer, T-Mobile

“At T-Mobile, protecting customers is fundamental to who we are. Our industry connects families, businesses, first responders and communities every day, so the security of our networks is a responsibility that extends beyond any single company”

“With stakes that high, we couldn’t work at the normal pace. The attackers never stop moving, so our teams skipped the pilots and the multi-year rollouts and moved at a speed most companies wouldn’t try. Today, phishing-related credential compromises among our people are down more than 99%. This report shows what it meant to move that fast, and what we learned along the way.”

Jason Leigh, Senior Research Manager, IDC

“Many companies merely provide a litany of cybersecurity abbreviations or footnote security in financial filings with minimal detail on specific cybersecurity actions. T-Mobile is elevating the conversation with a level of detail that signals a security program built for operational maturity.”

Mark Clancy, SVP, Information Security Officer, T-Mobile

“Ultimately, cybersecurity is about protecting people.”

“We pushed to modernize our systems and strengthen how we detect and respond to threats. With tighter collaboration across our teams and partners, our defenses became stronger and our response faster than ever before. There’s no finish line in cybersecurity. The threat landscape will keep evolving, and so will we.”
